Lamar’s lawyer Rich Hutton entered the plea on his behalf on Wednesday as the 33-year-old did not appear in court, TMZ reports.

Entering his plea: Lamar Odom has pled not guilty following his DUI arrest on August 30

The website claims that a pre-trial date has been scheduled for next month.

Lamar has apparently been ordered to observe all laws until then.

The reality star was arrested after being pulled over just before 4am for driving too slow at 50mph on the 101 Freeway in the San Fernando Valley.

He was then held at Van Nuys police station on $15,000 bail but was later released from custody at 8.30am.

Odom did not immediately respond to police, passing three exits and driving erratically, TMZ reports.

He failed numerous field sobriety checks but refused all chemical tests, according to police.

Leland Tang, the California Highway Patrol public information officer, told Radar Online: 'Lamar Odom was driving 50 mph on the 101 freeway. He was driving in a serpentine manner which is pretty bad. That is like when the officer does a freeway break. Across all the lanes of the freeway. I’m surprised he wasn’t rear ended.'

After 'failing' field sobriety tests, he was taken into custody and Tang said: 'He did what no one should ever do, he refused the chemical tests.

'That means that his license is revoked and Lamar could get the most powerful attorney in the world and he is still not going to have a license for a year.'
